Performance for item CRL1.25

At 1150 RPM and 100 psi differential pressure, the CRL1.25 pump requires 2.25 bhp (1.7 kW) to handle the rated fluid.

At 1150 RPM and 100 psi differential pressure, the CRL1.25 pump delivers 10 gpm (38 lpm) of the rated fluid.

Item Overview for Blackmer CRL1.25
The Blackmer CRL1.25 is a 1.25" high-speed sliding vane pump finished in ductile iron construction. Mechanical seals work alongside Buna-N elastomers to contain aggressive media and resist chemical attack. Installation stays simple thanks to tapped ports that match common piping practice. Overpressure protection arrives built in, with an internal relief valve shielding the casing and downstream piping. Supplied as a bare unit, it drops into an existing drive arrangement or a purpose-built skid. As part of the CRL lineup, it shares parts and service procedures with the rest of the range. Capacity extends to 15 GPM, shortening load and unload cycles. The drivetrain pairs a four-vane rotor turning right-hand with laminate vanes, keeping volumetric efficiency stable between rebuilds. Balanced running reduces stress on couplings, drives, and connected piping.
